This winsome story takes the premise of a child's first animal-identification picture dictionary (in fact the crossed-out title on the cover is My First Animal Book; the title is written beneath it in crayon) that has been hijacked by the first animal presented in the book: a dog...If readers aren't laughing out loud by now, they aren't ready for this kind of metafictive play—give it a few months and bring it back out. A clever, wonderfully silly, delightful romp.
—Kirkus Reviews

With bright-colored backdrops, Collins’s silly scenes focus all the attention on the titular dog, whose troublemaking manages to introduce a bit of meta fun.
